Removing key from macbook

So I have a piece of glitter stuck under the fn key key of my keyboard, I was just wondering how I go about removing the keys. I tried for a little with a screwdriver but it didn't seem like it wanted to go and I didn't want to push it too hard.

So does anyone know if there's a proper way to remove keys from the keyboard?

thanks

Cheers, I did manage to get the key off, but as for the glitter I only managed to push it into the case. Ahh well at least you can't see it anymore
